- * <p>
- * Android just doesn't support installing Apps that define long-lived Services
- * and/or own Account types onto the SD card. The documentation says not to do
- * it. There are hordes of developers who want to do it, and have tried to
- * register for almost every "package installation changed" broadcast intent
- * that Android supports. They all explicitly state that the package that has
- * changed does *not* receive the broadcast intent, thereby preventing an App
- * from re-establishing its state.
- * <p>
- * <a href="http://developer.android.com/guide/topics/data/install-location.html">Reference.</a>
- * <p>
- * <b>Quote</b>: Your AbstractThreadedSyncAdapter and all its sync functionality
- * will not work until external storage is remounted.
- * <p>
- * <b>Quote</b>: Your running Service will be killed and will not be restarted
- * when external storage is remounted. You can, however, register for the
- * ACTION_EXTERNAL_APPLICATIONS_AVAILABLE broadcast Intent, which will notify
- * your application when applications installed on external storage have become
- * available to the system again. At which time, you can restart your Service.
- * <p>
- * Problem: <a href="http://code.google.com/p/android/issues/detail?id=8485">that intent doesn't work</a>!

-/**
- * Our hacky version of transactional semantics. The goal is to prevent
- * the following situation:
- *
- * * AAA is not modified locally.
- * * A modified AAA is downloaded during the storing phase. Its local
- *   timestamp is advanced.
- * * The direction of syncing changes, and AAA is now uploaded to the server.
- *
- * The following situation should still be supported:
- *
- * * AAA is not modified locally.
- * * A modified AAA is downloaded and merged with the local AAA.
- * * The merged AAA is uploaded to the server.
- *
- * As should:
- *
- * * AAA is modified locally.
- * * A modified AAA is downloaded, and discarded or merged.
- * * The current version of AAA is uploaded to the server.
- *
- * We achieve this by tracking GUIDs during the storing phase. If we
- * apply a record such that the local copy is substantially the same
- * as the record we just downloaded, we add it to a list of records
- * to avoid uploading. The definition of "substantially the same"
- * depends on the particular repository. The only consideration is "do we
- * want to upload this record in this sync?".
- *
- * Note that items are removed from this list when a fetch that
- * considers them for upload completes successfully. The entire list
- * is discarded when the session is completed.
- *
- * This interface exposes methods to:
- *
- * * During a store, recording that a record has been stored, and should
- *   thus not be returned in subsequent fetches;
- * * During a fetch, checking whether a record should be returned.
- *
- * In the future this might also grow self-persistence.
- *
- * See also RepositorySession.trackRecord.

-   * Some notes on reparenting/reordering.
-   *
-   * Fennec stores new items with a high-negative position, because it doesn't care.
-   * On the other hand, it also doesn't give us any help managing positions.
-   *
-   * We can process records and folders in any order, though we'll usually see folders
-   * first because their sortindex is larger.
-   *
-   * We can also see folders that refer to children we haven't seen, and children we
-   * won't see (perhaps due to a TTL, perhaps due to a limit on our fetch).
-   *
-   * And of course folders can refer to local children (including ones that might
-   * be reconciled into oblivion!), or local children in other folders. And the local
-   * version of a folder -- which might be a reconciling target, or might not -- can
-   * have local additions or removals. (That causes complications with on-the-fly
-   * reordering: we don't know in advance which records will even exist by the end
-   * of the sync.)
-   *
-   * We opt to leave records in a reasonable state as we go, applying reordering/
-   * reparenting operations whenever possible. A final sequence is applied after all
-   * incoming records have been handled.
-   *
-   * As such, we need to track a bunch of stuff as we go:
-   *
-   * • For each downloaded folder, the array of children. These will be server GUIDs,
-   *   but not necessarily identical to the remote list: if we download a record and
-   *   it's been locally moved, it must be removed from this child array.
-   *
-   *   This mapping can be discarded when final reordering has occurred, either on
-   *   store completion or when every child has been seen within this session.
-   *
-   * • A list of orphans: records whose parent folder does not yet exist. This can be
-   *   trimmed as orphans are reparented.
-   *
-   * • Mappings from folder GUIDs to folder IDs, so that we can parent items without
-   *   having to look in the DB. Of course, this must be kept up-to-date as we
-   *   reconcile.
-   *
-   * Reordering also needs to occur during fetch. That is, a folder might have been
-   * created locally, or modified locally without any remote changes. An order must
-   * be generated for the folder's children array, and it must be persisted into the
-   * database to act as a starting point for future changes. But of course we don't
-   * want to incur a database write if the children already have a satisfactory order.
-   *
-   * Do we also need a list of "adopters", parents that are still waiting for children?
-   * As items get picked out of the orphans list, we can do on-the-fly ordering, until
-   * we're left with lonely records at the end.
-   *
-   * As we modify local folders, perhaps by moving children out of their purview, we
-   * must bump their modification time so as to cause them to be uploaded on the next
-   * stage of syncing. The same applies to simple reordering.

-   *
-   * Additionally, the mobile root is annotated. In Firefox Sync, PlacesUtils is
-   * used to find the IDs of these special folders.
-   *
-   * We need to consume records with these various GUIDs, producing a local
-   * representation which we are able to stably map upstream.
-   *
-   * Android Sync skips over the contents of some special GUIDs -- `places`, `tags`,

- * * Any outstanding records -- the ones we moved to "Orphans" -- are true orphans.

- *   We achieve the latter by bumping its mtime. The caller should take care of untracking it.

- * Note that we make no particular effort to handle repositioning or reparenting:

-/**
- * Record is the abstract base class for all entries that Sync processes:
- * bookmarks, passwords, history, and such.
- *
- * A Record can be initialized from or serialized to a CryptoRecord for
- * submission to an encrypted store.
- *
- * Records should be considered to be conventionally immutable: modifications
- * should be completed before the new record object escapes its constructing
- * scope. Note that this is a critically important part of equality. As Rich
- * Hickey notes:
- *
- *   … the only things you can really compare for equality are immutable things,
- *   because if you compare two things for equality that are mutable, and ever
- *   say true, and they're ever not the same thing, you are wrong. Or you will
- *   become wrong at some point in the future.
- *
- * Records have a layered definition of equality. Two records can be said to be
- * "equal" if:
- *
- * * They have the same GUID and collection. Two crypto/keys records are in some
- *   way "the same".
- *   This is `equalIdentifiers`.
- *
- * * Their most significant fields are the same. That is to say, they share a
- *   GUID, a collection, deletion, and domain-specific fields. Two copies of
- *   crypto/keys, neither deleted, with the same encrypted data but different
- *   modified times and sortIndex are in a stronger way "the same".
- *   This is `equalPayloads`.
- *
- * * Their most significant fields are the same, and their local fields (e.g.,
- *   the androidID to which we have decided that this record maps) are congruent.
- *   A record with the same androidID, or one whose androidID has not been set,
- *   can be considered "the same".
- *   This concept can be extended by Record subclasses. The key point is that
- *   reconciling should be applied to the contents of these records. For example,
- *   two history records with the same URI and GUID, but different visit arrays,
- *   can be said to be congruent.
- *   This is `congruentWith`.
- *
- * * They are strictly identical. Every field that is persisted, including
- *   lastModified and androidID, is equal.
- *   This is `equals`.
- *
- * Different parts of the codebase have use for different layers of this
- * comparison hierarchy. For instance, lastModified times change every time a
- * record is stored; a store followed by a retrieval will return a Record that
- * shares its most significant fields with the input, but has a later
- * lastModified time and might not yet have values set for others. Reconciling
- * will thus ignore the modification time of a record.

-/**
- * Batching Downloader, which implements batching protocol as supported by Sync 1.5.
- *
- * Downloader's batching behaviour is configured via two parameters, obtained from the repository:
- * - Per-batch limit, which specified how many records may be fetched in an individual GET request.
- * - Total limit, which controls number of batch GET requests we will make.
- *
- *
- * Batching is implemented via specifying a 'limit' GET parameter, and looking for an 'offset' token
- * in the response. If offset token is present, this indicates that there are more records than what
- * we've received so far, and we perform an additional fetch. Batching stops when either we hit a total
- * limit, or offset token is no longer present (indicating that we're done).
- *
- * For unlimited repositories (such as passwords), both of these value will be -1. Downloader will not
- * specify a limit parameter in this case, and the response will contain every record available and no
- * offset token, thus fully completing in one go.
- *
- * In between batches, we maintain a Last-Modified timestamp, based off the value return in the header
- * of the first response. Every response will have a Last-Modified header, indicating when the collection
- * was modified last. We pass along this header in our subsequent requests in a X-If-Unmodified-Since
- * header. Server will ensure that our collection did not change while we are batching, if it did it will
- * fail our fetch with a 412 (Consequent Modification) error. Additionally, we perform the same checks
- * locally.

-/**
- * Uploader which implements batching introduced in Sync 1.5.
- *
- * Batch vs payload terminology:
- * - batch is comprised of a series of payloads, which are all committed at the same time.
- * -- identified via a "batch token", which is returned after first payload for the batch has been uploaded.
- * - payload is a collection of records which are uploaded together. Associated with a batch.
- * -- last payload, identified via commit=true, commits the batch.
- *
- * Limits for how many records can fit into a payload and into a batch are defined in the passed-in
- * InfoConfiguration object.
- *
- * If we can't fit everything we'd like to upload into one batch (according to max-total-* limits),
- * then we commit that batch, and start a new one. There are no explicit limits on total number of
- * batches we might use, although at some point we'll start to run into storage limit errors from the API.
- *
- * Once we go past using one batch this uploader is no longer "atomic". Partial state is exposed
- * to other clients after our first batch is committed and before our last batch is committed.
- * However, our per-batch limits are high, X-I-U-S mechanics help protect downloading clients
- * (as long as they implement X-I-U-S) with 412 error codes in case of interleaving upload and download,
- * and most mobile clients will not be uploading large-enough amounts of data (especially structured
- * data, such as bookmarks).
- *
- * Last-Modified header returned with the first batch payload POST success is maintained for a batch,
- * to guard against concurrent-modification errors (different uploader commits before we're done).
- *
- * Non-batching mode notes:
- * We also support Sync servers which don't enable batching for uploads. In this case, we respect
- * payload limits for individual uploads, and every upload is considered a commit. Batching limits
- * do not apply, and batch token is irrelevant.
- * We do keep track of Last-Modified and send along X-I-U-S with our uploads, to protect against
- * concurrent modifications by other clients.

-/**
- * Pulls records from `source`, applying them to `sink`.
- * Notifies its delegate of errors and completion.
- *
- * All stores (initiated by a fetch) must have been completed before storeDone
- * is invoked on the sink. This is to avoid the existing stored items being
- * considered as the total set, with onStoreCompleted being called when they're
- * done:
- *
- *   store(A) store(B)
- *   store(C) storeDone()
- *   store(A) finishes. Store job begins.
- *   store(C) finishes. Store job begins.
- *   storeDone() finishes.
- *   Storing of A complete.
- *   Storing of C complete.
- *   We're done! Call onStoreCompleted.
- *   store(B) finishes... uh oh.
- *
- * In other words, storeDone must be gated on the synchronous invocation of every store.
- *
- * Similarly, we require that every store callback have returned before onStoreCompleted is invoked.
- *
- * This whole set of guarantees should be achievable thusly:
- *
- * * The fetch process must run in a single thread, and invoke store()
- *   synchronously. After processing every incoming record, storeDone is called,
- *   setting a flag.
- *   If the fetch cannot be implicitly queued, it must be explicitly queued.
- *   In this implementation, we assume that fetch callbacks are strictly ordered in this way.
- *
- * * The store process must be (implicitly or explicitly) queued. When the
- *   queue empties, the consumer checks the storeDone flag. If it's set, and the
- *   queue is exhausted, invoke onStoreCompleted.
- *
- * RecordsChannel exists to enforce this ordering of operations.

-
-============
-Architecture
-============
-
-CloudSync offers functionality similar to Firefox Sync for data sources. Third-party addons
-(sync adapters) consume local data, send and receive updates from the cloud, and merge remote data.
-
-
-Files
-=====
-
-CloudSync.jsm
-    Main module; Includes other modules and exposes them.
-
-CloudSyncAdapters.jsm
-    Provides an API for addons to register themselves. Will be used to
-    list available adapters and to notify adapters when sync operations
-    are requested manually by the user.
-
-CloudSyncBookmarks.jsm
-    Provides operations for interacting with bookmarks.
-
-CloudSyncBookmarksFolderCache.jsm
-    Implements a cache used to store folder hierarchy for filtering bookmark events.
-
-CloudSyncEventSource.jsm
-    Implements an event emitter. Used to provide addEventListener and removeEventListener
-    for tabs and bookmarks.
-
-CloudSyncLocal.jsm
-    Provides information about the local device, such as name and a unique id.
-
-CloudSyncPlacesWrapper.jsm
-    Wraps parts of the Places API in promises. Some methods are implemented to be asynchronous
-    where they are not in the places API.
-
-CloudSyncTabs.jsm
-    Provides operations for fetching local tabs and for populating the about:sync-tabs page.
-
-
-Data Sources
-============
-
-CloudSync provides data for tabs and bookmarks. For tabs, local open pages can be enumerated and
-remote tabs can be merged for displaying in about:sync-tabs. For bookmarks, updates are tracked
-for a named folder (given by each adapter) and handled by callbacks registered using addEventListener,
-and remote changes can be merged into the local database.
-
-Versioning
-==========
-
-The API carries an integer version number (clouySync.version). Data records are versioned separately and individually.

-CloudSync is a service that provides access to tabs and bookmarks data
-for third-party sync addons. Addons can read local bookmarks and tabs.
-Bookmarks and tab data can be merged from remote devices.
-
-Addons are responsible for maintaining an upstream representation, as
-well as sending and receiving data over the network.
